minimum temp for Nerine?

I am repotting my nerines, and checked the wiki for some information
about several of the species I am growing from seed.

I also read the information about sarniensis, and was startled by this:

Studies from the Netherland reports that it takes 3 years for a
developing bud to mature and that temperatures below 17C causes buds
to abort (which means it will take another 3 years to flower again if
it got too cold one winter and all the developing buds abort). Optimal
flowering temperature is 17-21C

I frequently experience temperatures below 17 C in the summer, never
mind the winter. It is noon now, on a sunny day, and the temperature
is 19 C, but at 7 a.m. it was 10.

The greenhouse in which my nerines live is several degrees above
ambient temperature, and never freezes, but there are many months when
it never gets anywhere near 17 C.

Does this explain why my sarniensis hybrids don't bloom frequently?
Do I need to keep them in one of the heated rooms in my house? (the
bedrooms aren't heated) Oh, that won't work. I just checked and the
living room is currently 20.

So - do I give up on them entirely?
